1 Specification of Letters Patent.

Patented Jan. 6, 1920.

Application filed August 19, 1918. Serial No. 250,492.

To all whom it may concern:

Be it known that I, EDMOND KELLEY, a citizen of the United States, residing at Boston, in the county of Suffolk and State of Massachusetts. have, invented new and useful Improvements iinHydropower-Beaters, of which the following is a specification.

The present invention relates to machines adapted to stir, whip, or beat liquid and semi-liquid fluids and compositions for such purposes as to produce a froth, thoroughly mix a number of ingredients or separate butter fat from cream and so forth; and its principal object is to, furnish an improved machine of this typej which is driven by water power and by." which the energy in the water is converted into work more efficiently and with smaller expenditure of water than other devices of similar type heretofore suggested. Further objects are to provide such machine with provisions by which the machine may be mounted upon and supported by the water tap or faucet of a domestic plumbing system, and with means byv which the waste water from the motor may be discharged against the outside of the jar or container in which the liquid is confined and on which themotor is mounted. f

The invention consists in the machine hereinafter described in detail in the following specification, and in all equivalents thereof and the principles underlying the same as pointed out in the appended claims; In the drawings, Figure 1 is an elevation of a machine embodying my invention in the form which at present I prefer to;others, Fig. 2 is a plan view of the machine shown in Fig.- 1, but represented with the outer casing or guard removed. Fig. 3 is' in part an elevation and inpart a vertical sect1on,

on a larger .scale than Fig. l, of the motor of the machine and the connections andconduits by whicha supply of water is directed thereto. Fig. 4 is a cross section ort'line The same reference characters indicate the same parts in all the figures.

In the drawings 11 represents a jar or container, which is preferably of glass and desired size and shape.-

whi'ch may be of any That here shown is a cylindrical jar of about one. quart capacity. 12 is the cover of the jar, which is here shown as a screw cap of familiar type adapted to be engaged with threads formed on the jar surroundinglits adapted the having widely separated at their lower ends where ed part.

' mouth. Instead of this specificcover, however, one of any other desired form'applied and secured in any other desired way may be used. 13 represents a dasher or beater which is contained within the'jar 11 and is to stir and agitate the contents of -The specific beater here shown is' made of a number of Wires having such length and being so bent as to produce the desired effect, and secured to a shaft 1 1. Any other specific form of beater, or dasher suitable for any other particular use to which the machine is intended to be put, may be used in place of the one shown.

Preferably the dasher is adjustable so'as to act in different vertical zones of the jar, and to make it so its shaft may be telescopic, consisting of a sleeve to which the numeral 14 is applied, and a driving shaft 15 which enters such' sleeve, and on which the latter is adapted to slide endwise. Any other form of adjustable and contractible shaft, or any other means for adjusting the dasher may be used, however, without departing from the invention.

Said cover 12 is the supporting base for the motor now about to be described and upon it there asthey may interior passageways,

otherwise be described, posts which are they are secured to the cover, and are brought together at their upper ends, making an A-shaped frame. There may be more than two of these tubes or posts, if desired, or only one; but I prefer two, for various reasons. Their upper ends are connected to, and their passageways open into, a connection 17 which is externally threaded downward from its upper end and has an outstanding flange or ledge 18 below its thread- The=fitting 17 may for the purpose of this description be called a nipple.

On the central part of the cover or base 12, between the posts 16 is a raised pedestal 19 which has a recess 20 in its upper face rarest sures.

are mounted two tubes 16, or

adapted to contain a series of balls 21, and

forming thus a race for a ball bearing. Preferably suchpedestal is formed out of sheet metal, which may be integral with the cover, the latter being also of sheet metal, or it may be of a separate piece suitably attached to the cover, and the ball race is preferably made by forming the sheet metal pedestal as shownin the left hand side of Fig. 3. Other constructions may, however,

hydraulic turbines,

race described, and has attached to it a plate 23 and a series of vanes 24:. Said plate 23. rests upon the balls 2-1, and is provided with a flange 25 which extends below the top of the pedestal and guards the ball hearing to prevent entrance of water thereinto. Preferably a hard wear plate or washer 26 is secured to the under side of the plate 23 and engages directly with the balls. 27 designates a spacing ring for the balls which surrounds the shaft, but is not connected thereto, and has a number of equally spaced pockets receiving the balls freely and spacing them at proper distances from one another in the ball race.

Preferably the plate 23 and flange 25 are made in one piece out of sheet metal, and the .vanes 24: are also made of sheet metal pieces soldered at their inner edges to the Shaft and at their lower edges to the plate 23. The upper end of the'shaft turns in a step bearing 28 fixed between the upper ends of the posts 16. j

The posts have openings 29 forming nozzles through which jets of water may issue, and being placed to. direct such jets against the vanes, in the most efficient direction, and the vanes are preferably curved according to principles familiar in connection with and as indicated in Fig. 2, whereby to utilize efiiciently the velocity and momentum of the jets. Said nozzles 29 are tangential to lines concentric with the shaft and intermediate the inner and outer ed es of the vanes.

he vanes and tubular posts, with their nozzles, constitute a hydromotor of which the vanes form the rotor connected to the shaft and supported by a ball bearing. This entire motor is mounted uponthe cover 12 and forms substantially a part thereof. Means for detachably connecting the posts 16 to the cover are shown in F ig. 3 as con-. sisting of screws 30 passing through the cover into the ends of the posts.

31 is aguard made preferably of sheet metal formed to surround rather closely the motor and having a lip 32 at its upper end which rests on the flange 1'8, and is secured thereon by a coupling 33 and an interposed packing washer 34:. Said coupling is screwed upon the nipple 17 and extends above the same, being internally threaded so that it may be screwed upon a threaded faupoint of view the joint between itself and the faucet. The guard 31 thus described confines the waste water thrown off from the motor and guides it downward. The lower edge of the guard is formed with an inwardly curved or inclined lip 37 which checks the velocity of the escaping water and also directs such water against the jar, so that it flows down the outer surfaces of the jar without spattering, and with the effect of cooling the contents of the jar. This lip is preferably far enough below the cover to insure that water will not be directed against the joint between the cover and the niouth of the jar.

It will readily be understood that when the jar containingfluid to be mixed or beaten is attached to the cover 12, and the latter is connected by the coupling 33 with a water faucet, and the faucet is opened, the water then flowing will drive the dasher, and then flow down along the outer surface of the jar. I have found that the ordinary service pressure with which houses are supplied from a central station gives sufiicient volume and velocity of water from the nozzles to drive the dasher with suflicient force and speed to beat anything which it may be de-' sired to beat or stir in a device of this sort rapidly and efficiently; and that the amount of water used is very small. The discharge capacity of all the nozzles together is much less than the full capacity of the common faucet or tap, wherefore the amount of water expended in the short time needed to carrl i out any beating operation is extremely sma the several parts of the machine here shown has been adopted as satisfactory from the of operativeness, compactness, and pleasing appearance. The posts have been shaped to diverge from the nipple on straight lines in order to impede the flow of water through the interior passageways as'little as possible, and the vanes have been shaped to conform to the space between these posts; while the formed to the outlines other form or design of these parts may be made Without departing from the essentials of the invention as hereinafter claimed. So also may the rotor be made otherwise than as separate sheet metal vanes shaped and mounted as described and shown.
